IMPROVEMENT IN CASTING, uMBRELLA-TIPS, ac.

Specification forming part of Letters Patent No. 166,282, dated August3, 1875; application tiled April 19, 1875.

To all whom it may concern: y

Be it known that I, AnoLPHUs LIGIBEL, of Jersey City,in the county ofHudson and State of New Jersey, have invented an Improvement in CastingUmbrella Tips, Heads, and Laps, of which the following is aspeciiication:

Ei'orts have been made to cast the laps or connecting pieces upon theribs of umbrellas; but they have not been successful, in consequeuce ofthe inaccuracy of workmanship.

In the manufact-ure of umbrella-frames it is necessary that the distancebetween the hole at the end for the crown-wire and the lap or joint forthe stretcher be exactly the same in each rib, and that the holes beparallel with each other,- otherwise the ribs will not lie close to andparallel with the stick or handle.

My machine is made for the purpose of rapidly casting the tips, heads,and laps upon umbrella-ribs, and at the same time insuring greataccuracy in the manufacture.

I make use of a machine somewhat like a type-casting machine, andcombine therewith a compound jaw or mold, of' an internal shapecorresponding with the external shape of the tip, head, or lap,and amovable mandrel, forming a core for the hole that is made in the lap,head, or tip, when cast.

I also employ a gage to determine the position of the lap, tip, and headin relation to each other.

In the drawing, Figure lis a front elevation of the machine. Fig. 2 is aplan. Fig. 3 is a plan view of the lower die, showing a rib in place forhaving a tip cast thereon; and Fig. 4 is a cross-section of the dies asclosed, with Fig. 5 is a plan view of the lower die, with a rib in placefor having a lap cast thereon.

The frame a carries the bath b, of type or similar metal, that is to bekept in a melted state by gas-burners or otherwise; and c is theactuating-shaft, that is provided with the cam d, acting upon the leverd to operate the pump e through the agency of the lever e', link f, andspring f', in a manner corresponding generally to that in a typecastingmachine; and

a bent lever, g, cam 3, spring 4', lever g', and sliding pointed valveworking within the nipple z' serve to close the orifice of said nipplewhen the molds are drawn away. The mold-V v One is in the adjustableblock o1, that is hinged at 18, and positioned4 by 4the screw 20, andclamped by the screws 19. The other half of the mold o is fastened tothe swinging head o2,

that is connected by the frked joint 48 to the block o1, and positionedby the end ot' such head oZ passing through the joint-block 28, andbeing clamped therein, when in place, by the screw 13. Upon theA.mold-frame h is a bent lever, r, pivoted at 16, and swinging behindthe guide-bar s by the action of the link s', that is attached at thelower end I7, at a distance from the pivots 4 of the frame h, and at theupper end to the'said lever r, so that, as the mold-frame is swung backtoward the nipple i upon the bath b, the bent lever r will be pulleddown at its moving end, and, by the link u, will close the mold. Thislink is pro vided with the adjusting rod and nuts u', the

horizontal end of'which rod passes into a hole in the head o2, and isretained by the notched lever c.

This construct-ion. allows the link to be dis connected from the head,so that that can be swung back to open the mold for cleaning orotherwise.

The molds themselves are made ofthe shape required for the tip at oneend, .and the head of the other, or for the lap in the middle ot' therib. (These forms are represented in the detached views.)

It is preferable to cast the middle lap or joint-piece first, and inthat case the straight `steel wire is passed in between the molds o andthe end stops against the adjustable gage t upon the arm 2l, the facesof the molds containing half-ronnd grooves to receive such steel rib,and the mold being shaped as shown to form the lap; bul-.it`isupreferable, both on account of expense and to insure accuracy, tocast the lap with the joint-hole in it, and for this purpose a pin, 24,is inserted up through the lower die, and thc end passes into a hole inthe upper die, so that the metal will be cast around that pin. (See Fig.4.) This pin has to be Withdrawn from the lap or tip, and for thispurpose the lever 26 is employed, and the link 27 to the lever fr, sothat the pin is projected up through the mold as the mold closes andmoves toward the teat on the bath of melted metal; and after the tip,head, or lap has been east by the jet of melted metal forced into themold by the pump, and the mold is being drawn back and opened, the pinis drawn down out of the hole in the cast lap or tip.

In casting the tip and head, the steel rib is insertedinto the mold inthe direction shown in Figs. 3 and 4, and the lap rests upon theadjustable gage t, so that its exact position is determined in relationto the tip that is cast v upon the end of the rib.

. The arm 21, upon which the adjustable gage in Fig. 3; or a second armmay be provided.

I claim as my inventionl. The two-part mold o, connected respectively tothe swinging mold-frame h and swinging head o2, in combination with suchframe h, swinging head 02, bent lever r, and link u, for opening andclosin g the mold, substantially as specified.

2. In combination with the two-part mold o, the pin 24, lever 26, link27, lever fr, and link s', as and for the purposes set forth.

3. The combination, with the molds o and casting mechanism, of theadjustable gage t and arm 2l, for positioning and holding the rib, asset forth.

Signed by me this 14th day of April, A. D. 1875.
